Burning Mg in the air and reacting with O2 forming a white powder of MnO
So the equation is going to be:
Mn + O2 ⇒ MnO (this equation is not conserved)
to make it equilibrium:
1- First we should put 2Mno to equal the O2 on both sides.
So it will be:
Mg + O2⇒ 2MgO
2- Second we should put 2Mn to equal the Mn on both sides.
2Mg + O2⇒ 2MgO (this equation is conserved)
After putting the physical states the final equilibrium equation is going to be:
Δ
2Mg(s) + O2(g)⇒ 2MgO(s)
That you have to do better
Atoms of the same element but with different atomic masses are called isotopes. They possess a different atomic mass, due to the indifferent number of neutrons that the atoms of a given element have.
The answer is b. propel should be guided by the way of nature
Hey there !
The answer is C. build up of electrical charges by friction
Static electricity is a stationary electric charge, typically produced by friction, which causes sparks or crackling or the attraction of dust or hair.
Hope this helps !
